| 91 | II. Watchdog support |
| 92 | |
| 93 | For security reasons, the at91 watchdog is running at boot time and, |
| 94 | if deactivated, cannot be used anymore. |
| 95 | If you want to use the watchdog, you will need to keep it running in |
| 96 | your code (make sure not to disable it in AT91Bootstrap for instance). |
| 97 | |
| 98 | In the U-Boot configuration, the AT91 watchdog support is enabled using |
| 99 | the CONFIG_AT91SAM9_WATCHDOG and CONFIG_HW_WATCHDOG options. |
